Liquid crystal display panel motherboard

Abstract

The invention discloses a liquid crystal display panel motherboard. The liquid crystal display panel motherboard comprises a color film substrate, an array substrate which is opposite to the color film substrate, main frame sealing glue, auxiliary frame sealing glue and an auxiliary support; the main frame sealing glue, the auxiliary frame sealing glue and the auxiliary support are formed between the color film substrate and the array substrate; the position of the color film substrate, which is corresponding to the auxiliary frame sealing glue, is provided with a first segment difference repairing layer; the position of the array substrate, which is corresponding to the auxiliary frame sealing glue, is provided with a second segment difference repairing layer. According to the scheme of the liquid crystal display panel motherboard, when alignment and attachment are performed on the color film substrate and the array substrate, the maintained distance between the color film substrate and the array substrate can be equal after the auxiliary frame sealing glue and the main frame sealing glue abut against structural layers which are arranged on the color film substrate and the array substrate, so that non-uniform display at the edge of the display area due to the fact that the box thickness at the edge of the display area and the liquid crystal box thickness in the display area are unequal due to the fact that the stress of the color film substrate of the bilateral sides of the main frame sealing glue is uneven under the action of the external atmospheric pressure due to the segment difference of the main frame sealing glue and the auxiliary frame sealing glue is avoided.

Description

technical field [0001] The invention relates to the field of liquid crystal display technology, in particular to a liquid crystal panel motherboard. Background technique [0002] In the manufacturing process of the multi-sided cutting liquid crystal panel mother board in the prior art, after the color filter substrate and the array substrate are aligned, in order to maintain the uniformity of the cell thickness between the two substrates, prevent the color filter substrate and the array substrate from Misalignment occurs due to external force, which causes a drop in alignment accuracy and affects the display. A main sealant, an auxiliary sealant and an auxiliary column support are arranged between the two substrates. [0003] figure 1 It is a schematic diagram of the structure of the color filter (CF) substrate and the array (Arry) substrate after boxing in the prior art; figure 2 It is a cross-sectional view showing the position of line A-A between the color filter subs...

AI Technical Summary

Problems solved by technology

The color filter substrate close to the display area of ​​the main sealant 106 will warp upwards, causing the force of the color filter substrates on both sides of the main sealant 106 to be different, resulting in the thickness of the cell at the edge of the display area and the thickness of the liquid crystal cell in the display area. , resulting in display unevenness at the edge of the display area
